Abstract

The present study has been undertaken to investigate a process that removes inorganic mercury from waste water streams by use of a liquid membrane system in which a novel macrocyclic ligand based on dithio derivatized biscrown ether has been used as a cation carrier. The effect of temperature, stirring rate and different solvents on the kinetic parameters like k1, k2 and flux values J a max, J d max and tmax were also investigated. It was found that the membrane entrance rate constant (k1) and the membrane exit rate constant (k2) increased with increasing temperature and stirring rate. The membrane entrance rate constants (k1), exit rate constants (k2), as well as the flux values vary in the order of CH2Cl2 > CHCl3 > CCl4 in different solvents study
